A goose neck microphone is used when speaking announcements to a PA group or when sending
commands to SeaCom210 command units (talk-back). The microphone is activated by pressing
and holding down the SPEAK button.
Pressing ‘‘Speak’ or PTT on handset/headset while General Alarm is active, will override the GA
call and set up a PA call to the GA group. When released, GA will be re-connected.
’Mode’ selects between MODELESS, PA, COMMAND and ALARM CALL types of calls.
10 group buttons are available for selecting one or more PA groups if in PA mode. If in command
mode, up to 10 command groups can be addressed.
A monitor speaker with volume control is available, and indicator light for each button can be
dimmed using the dimmer control.
The SeaCom 310 is connected to the SeaCom 2000 via 4 wires. Two wires are used for signalling
and two for 24V DC power to the unit.
If used In a redundant system, additional 4 wires are connected. In this case the unit will be
powered from both systems.
This is to be used when two SeaCom 2000 systems are connected, implementing a redundant
PA/GA system.
A headset, handheld microphone or an extra monitor speaker can be connected. When a handheld
microphone is connected, the PTT button of the microphone acts as the ‘‘Speak’ button.
If only a handset or headset is used, the ‘Speak’ button on the unit can be disabled and the
gooseneck microphone omitted.
The PTT button can be set to automatically disconnect the PA call when released. Normally the
call is released by pressing ‘END’
A bell relay output is provided for connecting to an alarm device activated when the unit receives a
call. The relay can be set to either follow the ringing signal or hold the signal while ringing is
detected.

2. Using the SeaCom 310
Using the SeaCom310 Command Group Unit is straightforward, and will be described in the
following.
2.1 Front layout
The figure below shows the front of the SeaCom 310 unit.
Figure 2. Front layout and naming of keys and switches.
2.1.1 Group select buttons
The 10 group select buttons are used for selecting the PA, command or alarm groups.
To select a group, press the button and the associated indicator will be lit. Press the button once
again and the group will be deselected and the indicator will be off. Two or more groups can be
selected at the same time.
Selecting a group will cause the ‘Speak’ button to begin flashing to indicate that next step is to
press the ‘Speak’ button. Changing current setting will give the same indication.
If changing the current setting to no selected groups, the ‘Speak’ button will stop flashing and
become inactive.
Selecting an ambiguous combination of groups will cause the group indicators in question to start
flashing when the call is initiated. This is the case if a PA group is selected together with a
command group, an alarm group, or if more than one alarm group is selected.
Pressing the ‘End’ button 2 times sets all group keys off.

followed by a long tone.
If the system is set up to be a redundant PA/GA system, and the A system is not working, use the
B Monitor to monitor the alarm generator of the B system.
2.2.2 Modeless call
Press the ‘Mode’ button until no mode indicator is lit. Then select one or more groups. The
indicator light for each group selected will be lit. The modeless chart can contain numbers
associated to each group button that are in fact PA call numbers or alarm call numbers. That
depends on the actual programming of the SeaCom2000 system.
The following is valid selections:
•
One or more PA groups. If more than one group is selected, all groups will be seen as one
large group. However, the priority and signalling (the gong) tone will be chosen from the
PA group having the highest priority.
•
One or more Command groups
•
One single alarm group.
When a valid selection is set up, press the green ‘Speak’ button to start the call. The type of call
for the group in question will be indicated using the mode indicators if listed as e.g. PA call
numbers in the SeaCom2000 system.

2.2.3 Making a public address call
Choose the Public address mode using the ‘Mode’ button, or choose one or more PA groups in
modeless mode.
Press the green ‘Speak’ button and await the ‘gong’ sound to be sent. The monitor speaker will
monitor own ‘gong’ sound. When the ‘gong’ has ended, the green ‘Speak’ button will open the
microphone. The message can now be spoken into the gooseneck microphone. Releasing the
green ‘Speak’ button will mute the microphone or terminate the call depending on the
configuration of the SeaCom310 unit. If set to mute the microphone it will not terminate the PA
call. As long as the call is active and the speakers are open, the green ‘Speak’ button will be
steady lit. In order to terminate the public address announcement press the ‘End’ button.
NOTE : The PTT on the handset or headset will have the same function as ‘Speak’.
2.2.4 Setting up a command group call (talk-back)
Choose the Command mode using the ‘Mode’ button, or choose Command units or groups in
modeless mode.
Press the green ‘Speak’ button, and wait a couple of seconds for the command group to be set
up. If the command group is a ‘direct in’ (Refer to the ‘SeaCom2000 Configuration Manual’.), the
command group units has turned their speakers on and is ready for receiving the voice message
from the SeaCom310. Hold or press again the ‘Speak’ button and speak the message into the
gooseneck microphone. When the green ‘Speak’ button is released, the monitor speaker is used
to monitor the voice send from one of the speaking command units in the group.
Pressing a group select button representing a single SeaCom210 command unit, while ‘Speak’ is
released, will command speech direction to be from the SeaCom210 unit to the SeaCom310 unit.
The group select indicator will flash to indicate the unit is speaking. The speech direction can be
controlled using the ‘Speak’ button. All the other participants are listeners only.
In this way a command group can be controlled entirely from the SeaCom310 unit, and no manual
actions are to be taken at the SeaCom210 end. However, direction can still be controlled from the
SeaCom210 units.
Terminate the call by pressing the ‘End’ key.
NOTE : The PTT on the handset or headset will have the same function as ‘Speak’
2.2.5 Manual dial up

2.3 Receiving a call
The SeaCom 310 unit can also receive calls. Calls to the SeaCom 310 unit will typically be
initiated from a command group unit (SeaCom210) but can also be an ordinary extension or even
another SeaCom 310 unit. The monitor speaker will replicate the ringing signal but if that is not
power full enough an external sounder can be connected through a ringing relay inside the unit.
The relay output will replicate the ringing signal in order to make an audible ‘ringing’ signal.
Depending on the configuration of the SeaCom310 unit, it can either follow the ringing signal or
make a constant signal.
Replication of the ringing signal on the unit is delayed compared to the actual ringing signal from
the extension board in the SeaCom frame. The ringing relay will follow the ringing signal from the
extension board.
2.3.1 Normal incoming call
When a ringing signal is received, the green ‘Speak’button will begin flashing. Press the ‘Speak’
button to answer the call. Speak into the gooseneck microphone while pressing the ‘Speak’
button. Release the ‘Speak’ button in order to listen to the caller.
Terminate the call by pressing the ‘End’ button.
2.3.2 Direct in —command call
If a direct in call from an extension or another SeaCom310 unit, it will be indicated as a command
call. In this case audio will be connected direct through from caller and direction can be changed
by pressing ‘Speak’. However, the group buttons are disabled in this case.
Terminate the call by pressing the ‘End’ button or terminated automatically when caller
disconnects.
2.3.3 Direct in —PA call
The SeaCom310 unit can also be a member of a PA group. If paged by a PA call, only GA and
‘End’ can be pressed to end the call manually.
